PDF Reports are not generating in new Nagios XI Instance

[shoreypu]

I installed Google Chrome and updated /usr/local/nagiosxi/html/includes/utils-reports-export.inc.php, with mixed results.

When running a report manually and saving as PDF, the file wants to save as an html file.
If I add the .pdf extension, I get the following message, "You have used the extension “.pdf” at the end of the name. The standard extension is “.html”."
If I choose to change to PDF, I get an error using Edge and Chrome,
Using Edge: Couldn't download - No file.
Using Chrome: File wasn't available on site.

I get the same error if I simply try to download as an html file.

However, I was able to receive a report via email, as a PDF, successfully.

Thanks...John

Thanks for the update John,

I will pass along the difficulties you are having, so our developer can take a look.

Hi John,

I'm looking into this but I'm not seeing what you're describing on my system. Did you install the google-chrome-stable package mentioned in this thread?

Can you advise the steps you're taking to get this PDF download? I ask because when I generate a report and click on Download, and then the "PDF" option, I get redirected to a printable PDF view of the page within the Nagios XI window, which has a print option. I can either use the print functionality to print it to a local PDF, or click the "Download" icon to directly download the pdf, but in either case I get it in .pdf format, so I'm looking to confirm we're taking the same steps.

The only difference on my end is that I installed Google Chrome using a yum repo, and I confirmed that I am running google-chrome-stable.

rpm -qa | grep google-chrome-stable
google-chrome-stable-135.0.7049.95-1.x86_64

I also confirmed that line 164 in /usr/local/nagiosxi/html/includes/utils-reports-export.inc.php line reads as,
$bin = 'google-chrome-stable --headless=new --ignore-certificate-errors --enable-low-end-device-mode --disable-gpu --no-sandbox --virtual-time-budget=10000 --run-all-compositor-stages-before-draw';

I retested both Chrome and Edge and received the same results. Trying to Save As PDF, displays the file, then when I try to save that file, it wants to save as a file called managereports, which fails to download. If I try to change to a .PDF extension, I get the following prompt , "You have used the extension “.pdf” at the end of the name. The standard extension is “.html”." If I continue to try and save as a PDF, it also fails.

HERE'S the funny thing. I have now tested Firefox and that works and the file is named correctly by default, for example, statehistory-68013fca688c5.pdf.

So this issue seems to be related to using Chrome or Edge. The only way to get it to work there is to Print and Save as PDF.
